Abstract
A perforating gun includes a charge tube, a switch carrier body, and a pin contact spacer. The switch carrier body houses an addressable switch, a spring tube which holds a spring, a detonation block, a removable interrupter, and a pin contact spacer supporting a pin contact assembly. The spring biases a switch contact terminal towards an outer surface of the switch carrier body, and the switch contact terminal is electrically connected to the addressable switch. The interrupter includes first and second portions, and is temporarily adhered to the switch carrier body such that the first portion covers the switch contact terminal and the second portion extends between a detonation cord and an instantaneous detonator in the detonation block. A first end of the charge tube is positioned around the switch carrier body, and a second end of the charge tube is secured to the pin contact space.
